**v2.03.129** SDLS129 - CALCUL MODAL D'UNE ETOILE A 3 BRANCHES
==============================================================

**Summary:**

The objective of this test is to validate the correct consideration of substructure orientations in DEFI_MODELE_GENE, as well as the reproduction of complex generalized modes on a physical basis. A three-pointed star plan model is constructed, consisting of two distinct macro elements: a macro element for the central part of the star, and a macro element for the star branch.

Two models are carried out:

•Modeling A: calculation of real modes, without damping;

•B modeling: introduction of Rayleigh damping for the calculation of complex modes.
